Abstract: We study the nonequilibrium dynamics of relaxation and dressing of a mobile impurity with velocity $v$, suddenly immersed, or quenched, into a zero-temperature homogeneous Bose-Einstein condensate. A many-body generalization of Weisskopf-Wigner theory is implemented to… read more here.

DOI: 10.1103/physreva.97.052505
Abstract: The $K\ensuremath{\beta}$ x-ray spectra of the elements from Ca to Ge have been systematically investigated using a high-resolution antiparallel double-crystal x-ray spectrometer. Each $K{\ensuremath{\beta}}_{1,3}$ natural linewidth has been corrected using the instrumental function of this… read more here.

DOI: 10.1103/physrevb.102.174103
Abstract: The Johari-Goldstein secondary $(\ensuremath{\beta})$ relaxation is an intrinsic feature of glasses, which is crucial to many properties of disordered materials. One puzzling feature of $\ensuremath{\beta}$-relaxation is its wide relaxation peak, which could imply a critical… read more here.

DOI: 10.1103/physrevd.102.013004
Abstract: We investigate some consequences if neutrinoless double beta decays ($0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}\mathrm{s}$) of nuclei are dominated by short range interactions. To illustrate our results, we assume that $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}\mathrm{s}$ proceed mainly through short range interactions involving two-W-boson exchanges… read more here.

DOI: 10.1103/physrevmaterials.4.094404
Abstract: While the metastable $\ensuremath{\beta}$ (A15) phase of tungsten has one of the largest spin Hall angles measured, the origin of this high spin Hall conductivity is still unclear. Since large concentrations of oxygen and nitrogen… read more here.
